🛠️ Manual Installation Command List

1. Identify the Target Disk
   Determine the disk where you want to install the OS:

   lsblk
   # Example output: /dev/sda
   # Replace /dev/sdX with your actual target disk

2. Partition the Disk
   Create necessary partitions (e.g., root and swap):

   sudo fdisk /dev/sdX
   # Inside fdisk:
   # - 'g' to create a new GPT partition table
   # - 'n' to add a new partition (e.g., for root)
   # - 't' to set partition type (e.g., 20 for Linux filesystem)
   # - Repeat 'n' and 't' for additional partitions (e.g., swap)
   # - 'w' to write changes and exit

3. Format the Partitions
   Format the created partitions:

   sudo mkfs.ext4 /dev/sdX1  # Format root partition
   sudo mkswap /dev/sdX2     # Format swap partition

4. Mount the Root Partition
   Mount the root partition to /mnt:

   sudo mount /dev/sdX1 /mnt

5. Extract the Root Filesystem
   If you have a SquashFS image:

   sudo unsquashfs -f -d /mnt /path/to/rootfs.squashfs

   If you have a directory:

   sudo cp -a /path/to/rootfs/* /mnt/

6. Mount System Directories
   Prepare for chroot by mounting necessary filesystems:

   sudo mount --bind /dev /mnt/dev
   sudo mount --bind /proc /mnt/proc
   sudo mount --bind /sys /mnt/sys

7. Chroot into the New System
   Enter the new system environment:

   sudo chroot /mnt

8. Install GRUB Bootloader
   Install GRUB to make the system bootable:

   grub-install /dev/sdX
   update-grub

9. Configure fstab
   Generate and edit /etc/fstab with correct UUIDs:

   blkid
   # Use the output to populate /etc/fstab accordingly

10. Exit and Unmount
    Exit chroot and unmount filesystems:

    exit
    sudo umount /mnt/dev
    sudo umount /mnt/proc
    sudo umount /mnt/sys
    sudo umount /mnt

11. Reboot
    Restart the system:

    sudo reboot
